Examination

Learning Objectives

• Answer every section of the examination paper.
• Complete the practical task accurately within the time allowed.
• Apply the conventions of classification and description.
• Analyse the result and plan the Second Term revision.

Before the Examination

Arrive early and confirm that the practical computers are working. Lay out two pens, a pencil, an eraser, a ruler and the identification card. Read the whole instruction sheet before touching the keyboard.

During the Written Paper

The paper will include objective questions that test single facts, names and classifications. It will also include short answer questions that test definitions, differences and short explanations.

Answer every question. Begin with the ones you are sure of. In a classification question, write the group before each item. In a list question, number the items so that each can be marked.

During the Practical Paper

Work in the order given. Create the file, enter the content, format it as instructed, then save with the exact name in the exact folder. Save at each stage rather than only at the end.

Check the finished file against the task before the time ends: the required document or worksheet exists, the required formatting has been applied, and the file name matches the instruction.

After the Examination

The marked script is analysed by counting the marks lost on each question. A question that most learners missed identifies a topic to reteught in the Second Term.

The Second Term begins with revision of the weak topics and then moves to new work, which continues with programming, databases and networks.

Practical Work

1. Read the whole instruction sheet before starting the practical task.
2. Note the required file name, folder, data and formatting before typing.
3. Save the file at each stage of the task.
4. Check the finished file against every item in the instruction before the time ends.
5. Note the topics that felt weakest for the Second Term revision plan.

Scenario-Based Questions

1. Explain why classification questions should be answered with the group written before the item.
2. Describe how you would check a finished word processed document against the practical instruction.
3. A candidate has ten minutes left and the file has not been saved. Explain the order of priorities.
4. Explain how the result of the examination is used to plan the Second Term work.
5. Explain why a file saved under the wrong name earns no marks in a practical examination.
6. Explain the difference between a short answer question and an essay question.
7. A difference question carries four marks and a candidate writes only one half. Explain how the marks are awarded.

First Term Examination Practice Questions

These questions are taken from the First Term examination and Continuous Assessment papers for this class. Answer them in full sentences.

1. (a) Tabulate the major technological components, advantages, and limitations of the First, Second, Third, and Fourth Generations of computers. (b) A legacy file system uses 2,048 Bytes of storage. Convert this value into Kilobytes (KB) and further convert it into bits. Show complete calculations.
2. (a) Define Computer Science and Information and Communication Technology (ICT). (b) Distinguish clearly between Data and Information with two practical real-world examples of each. (c) If a text file contains 3,072 characters (assuming 1 character = 1 Byte), calculate its exact size in Kilobytes (KB). Show your step-by-step conversion.
3. (a) Trace the historical development of calculating devices by highlighting the contributions of the Abacus, John Napier, Blaise Pascal, and Charles Babbage. (b) Explain why Charles Babbage is regarded as the 'Father of Computers'. (c) Convert a storage measurement of 16 Megabits (Mb) into Megabytes (MB), recalling that 1 Byte = 8 bits. Show your workings.
4. (a) Classify computers based on operating principles (type) and explain each class with one example: Analog, Digital, and Hybrid. (b) Classify digital computers based on size and capability, describing Microcomputers, Minicomputers, Mainframe computers, and Supercomputers.
5. (a) Define Computer Hardware and categorize it into Input, Output, and Storage components. (b) Explain the primary functions of computer peripheral devices, giving specific attention to Scanners, Plotters, and Projectors. (c) Convert 10 Megabytes (MB) into Kilobytes (KB) and then calculate how many 512-byte blocks can fit into that 10 MB space.
6. (a) Differentiate clearly between Primary Memory and Secondary Storage, comparing RAM and ROM. (b) Perform the following storage scale conversions, showing all intermediate steps: (i) Convert 3 Gigabytes (GB) into Megabytes (MB). (ii) Convert 512 Bits into Bytes. (iii) Arrange the following storage capacities in descending order: 2 TB, 2,048 MB, 500 KB, 4,096 Bytes.

Lesson objectives

By the end of the examination week, learners should be able to:

1. Demonstrate recall of the term's concepts under examination conditions.
2. Apply knowledge to unfamiliar examples in objective and short-answer questions.
3. Complete a practical task within the time allowance using correct procedure.
4. Name, save and submit files correctly.
5. Explain their practical output when questioned by the examiner.

Examination design

For Senior Secondary 1 the totals are: Section A objective 20 marks, Section B short answer 30 marks, Section C essay 10 marks, Section D practical 20 marks, total 80. Section A samples recall. Section B samples explanation, comparison and classification. Section D samples practical skills in this term and advanced productivity tools.

Teacher activities

1. Confirm the approved timetable, venue, seating and invigilation before the week begins.
2. Brief learners on the paper structure, the time for each section and the materials allowed.
3. Set out three practical stations: typing, word processing and operating-system interaction, with one invigilator per station where possible.
4. Prepare offline equivalents for learners without device access: printed keyboard diagram, paper formatting task and OS scenario card.
5. Mark using the agreed scheme, moderate a sample of scripts and record scores.
6. Return scripts with feedback and prepare to hand over to Second Term.

Student activities

1. Attend the briefing and note the time allowed per section.
2. Complete Section A, then Section B, allocating time as instructed.
3. Move through the practical stations in the assigned order.
4. Save work with the correct filename and confirm it opens before leaving the station.
5. Answer the examiner's question on their practical output.
6. Collect marked scripts and record the topics to revise in Second Term.

Practical / learning evidence

The completed examination script, the saved practical file for each candidate and the practical rubric sheets. Retain scripts, marking guides and representative learner work for moderation as required by the assessment framework.

Resources and preparation

Printed question papers and answer sheets, a marking guide and rubric per station, working computers with Word or Writer, a stopwatch, printed keyboard diagrams and OS scenario cards. Check every machine the day before, and prepare two spare machines where possible. Ensure power backup and an offline alternative for each station.

Assessment for learning

Mark Section D against the practical rubric: task interpretation, procedure, technical accuracy, OS interaction, file naming and saving, organisation and explanation. Moderate a sample of scripts across all sections, and flag any question where more than a third of learners scored zero for review of the teaching rather than the learners.

Inclusion and access

Provide extra time and large-print papers where approved, seat learners with visual or hearing needs appropriately, and allow the offline equivalent for any learner without device access so that no candidate loses practical marks because of equipment. Keep the practical criteria identical across the digital and paper routes.

After the examination

Record scores against the class list, return scripts with brief feedback, and hand over to Second Term: problem solving, flowcharts, pseudocode, types of programming languages, translators, program development, communication systems, internet benefits and abuse, computer ethics and viruses, applications of ICT. Note any topic where the class average fell below the school's threshold and schedule it as a Second-Term retrieval starter.
